FIELD OF THE INVENTION

The present invention relates generally to trays for holding portabledevices, and in particular to quick release docking stations forportable computers and other portable electronics devices having one ormore input/output (I/O) communication ports.

BACKGROUND OF THE INVENTION

Portable notebook-type computers using a built-in battery pack powersource are generally well-known and have an advantage in being handy tocarry about and freely used even in those places which are notaccessible to the commercial power supply.

Such computers are compact in design for higher portability, so thattheir standard functions are inevitably more limited than those ofdesktop computers. Accordingly, such portable computers are generallyprovided with one or more connectors and ports for function expansion,usually on the rear face of its casing which supports a keyboard and adisplay unit. These computers are additionally furnished with newfunctions by connecting peripheral devices, such as a hard disk drive,mouse, printer, etc., to the connectors and ports.

FIGS. 1 and 2 illustrate a notebook-type portable computer 1 for use asa portable electronic device which is connected to an external expandingapparatus, commonly referred to as a “docking station.” The computer 1includes a plastic casing 2 serving as an apparatus body. The casing 2is in the form of a flat generally rectangular box having a bottom face2 a and a top face 2 b, which extend generally parallel to each other,and a front face 2 c, a rear face 2 d, and side faces 2 e and 2 f, whichare continuous with the bottom and top faces 2 a and 2 b. At least onesuch computer casing 2 further includes a tongue 2 g projected from thefront face 2 c and having a bottom face 2 h which may be continuous withthe bottom face 2 a of the casing 2, a top face 2 i which extendsgenerally parallel to the bottom face 2 h, and a front face 2 j that isspaced away from the casing front face 2 c. The tongue 2 g may includeside surfaces 2 k and 2 l extending between the computer casing frontsurface 2 c and the tongue front face 2 j. Other surfaces of the casing2, such as one of the side faces 2 e, 2 f may includes additionalfeatures, such as but not limited to a CD-ROM or DVD-ROM 3 a and a mainpower switch 3 b.

Arranged on the top face 2 b of the casing 2, as illustrated in FIG. 1,is a keyboard 7 which is used to input information and commands. A pairof display supporting portions 8 a and 8 b, left and right, are formedat the rear end portion of the top face 2 b. A flat display unit 9having a thickness t is connected to the display supporting portions 8 aand 8 b. The display unit 9 is rotated about a hinge axis h on a pair oflegs 10 a and 10 b, left and right, which are pivotally mounted on thesupporting portions 8 a and 8 b, respectively, by means of hinge devicesas is generally well-known. Thus, the display unit 9 is supported on thecasing 2 to be rotatable about the hinge axis h relative to the casing 2between a closed position, in which a display screen surface 9 a of thedisplay unit 9 touches the top face 2 b of the casing 2. The displayunit 9 thereby covers the keyboard 7 for protecting both the keyboard 7and display screen surface 9 a of the display unit 9 with a hard shellbacking portion 9 b of the display unit 9. The display unit 9alternately rotates into an open position in which the display unit 9stands upright with the display screen surface 9 a exposed at the backof the keyboard 7, as illustrated. Furthermore, a hard shell lip portion9 c of the display unit 9 surrounds the sensitive display screen 9 d,the display screen 9 d is slightly recessed below the hard shell lipportion 9 c.

FIG. 2 illustrates an input/output (I/O) connector or port 4 of theknown portable computer being provided in the rear face 2 d betweeninterface apertures 4 a and 4 b on either side thereof. The I/Oconnector 4 includes a quantity of pins or pin receptors (shown) 4 c areorganized in a selected pattern. The pins or pin receptors 4 c providedinput/output (I/O) capability for communicating with various peripheralcomponents that may provide such functions as for example but notlimited to: a modem, a game port, audio output, a microphone input,serial connections, parallel connections, a video display output, USB(Universal Serial Bus) connection, a mouse connection, a keyboardconnection, an external power supply connection. Alternatively,connection to these or other peripheral devices are provided by aseparate and individual modem connector, a game port, audio speakerconnectors, a microphone connector, two serial connectors, a parallelconnector, a display unit connector, a USB connector, a mouse connector,a keyboard connector, and an external power supply connector, as aregenerally well-known in the art. A metallic terminal plate 5 is exposedon the rear face 2 d and surrounds the I/O connector 4 and includes anopen end of each of the apertures 4 a and 4 b. The apertures 4 a and 4 beach include a cylindrical aperture or a lengthwise slot (shown) or anaperture of another shape extending from the rear face 2 d of the casing2 toward the opposite front face 2 c.

In transporting the computer 1 peripheral devices must be removed fromtheir corresponding connectors or ports, or alternatively the single I/Oconnector 4. In restoring the computer 1 to its original state afterusing it elsewhere, any peripheral devices must be connected again viathe I/O connector 4. In the case where a large number of peripheraldevices are connected, therefore, the removal and connection requirevery troublesome operations.

To cope with this, there have recently been provided external expandingapparatuses or “docking stations” which are adapted to be interposedbetween a portable computer and a plurality of peripheral devices andrelay signals transferred between the computer and the devices.

FIG. 3 illustrates one such docking station 13 having a plurality ofconnectors and ports connectable with the peripheral devices, externalpower supply connector, etc., and an expansion connector 15 is presentedat a connector presentation surface 21 which is opposed to the rear face2 d of the computer casing 2. The expansion connector 15 is structuredto engage the computer's I/O connector 4. The expansion connector 15 ismounted on a movable bracket 18 structured to engage apertures 4 a and 4b on opposite sides of the I/O connector 4 as a prelude to the expansionconnector 15 actually engaging the I/O connector 4. By example andwithout limitation, the bracket 18 includes a pair of guide pins or arms18 a and 18 b that are positioned on opposite sides of the expansionconnector 15 to engage apertures 4 a and 4 b on opposite sides of theI/O connector 4. The expansion connector 15 includes a quantity of pinreceptors or pins (shown) 15 a organized in a selected pattern to engagethe pins or pin receptors 4 c of the computer's I/O connector 4. Thepins 15 a of the expansion connector 15 are connected electrically todifferent ones of the connectors and ports that are connectable with theperipheral devices.

In known prior art docking station devices 13 the pair of guide pins orarms 18 a and 18 b positioned on opposite sides of the expansionconnector 15 are extended forward of the expansion connector 15 and itspin receptors or pins (shown) 15 a such that the guide arms 18 a, 18 bengage the apertures 4 a and 4 b on opposite sides of the I/O connector4 before the expansion connector 15 and its pin receptors or pins 15 athe I/O connector 4. Furthermore, the expansion connector 15 istypically loosely mounted on the bracket 18 with a little lateral playsuch that the expansion connector 15 is permitted to move relative tothe bracket 18 and its pin receptors or pins (shown) 15 a wiggle or“float.” into final mating positions with the respective pin receptors(or pins) 4 c of the I/O connector 4 after the guide arms 18 a, 18 bhave established a nominal docking position. Thus, the guide arms 18 a,18 b with the respective interface apertures 4 a, 4 b fine tunes thepositioning of the pins (or pin receptors) 15 a of the expansionconnector 15 relative to the pin receptors (or pins) 4 c of thecomputer's I/O connector 4 prior to final insertion.

The docking station 13 also includes a mounting platform 17 on which thecomputer 1 is removably mounted. The mounting platform 17 is, forexample, adjacent connector presentation surface 21, and includes abearing surface 19 on which the bottom face 2 a of the computer casing 2is placed. The docking station apparatus 13 also includes bullet-nosedengaging pins 23 a and 23 b, which are provided on the bearing surface19 adjacent to the connector presentation surface 21. The bottom face 2a of the computer casing 2 includes a pair of locating holes 6 a and 6 bsituated adjacent to the rear face 2 d and the side faces 2 e and 2 f ofthe casing 2. The locating holes 6 a, 6 b each include a cylindricalaperture extending from the bottom face 2 a toward the opposite top face2 b and sized to accept the bullet-nosed engaging pins 23 a, 23 b on thebearing surface 19 of the docking station 13. The locating holes 6 a and6 b thus serve to locate the computer's I/O connector 4 relative to theexpansion connector 15 on the presentation surface 21 of the dockingstation 13.

In connecting the computer to the docking station 13, the tongue 2 g ofthe computer casing 2 is fit into a mouth 25 of a mating receiverstructure 27 adjacent to the bearing surface 19 opposite from and facingtoward the connector presentation surface 21. The computer casing 2 isrotated about the tongue 2 g with the bottom surface 2 a of the casing 2guided toward the bearing surface 19. When the bottom surface 2 a of thecasing 2 is close to the bearing surface 19, the mating locating holes 6a and 6 b in the bottom surface 2 a of the casing 2 engage the locatingpins 23 a, 23 b of the docking station 13, which positions the casing 2relative to the docking station 13, and in particular positions the I/Oconnector 4 relative to the docking station's expansion connector 15.

Thereafter, the docking station's expansion connector 15 and the pair ofguide pins or arms 18 a, 18 b on either side of the expansion connector15 are moved together in the direction indicated by the arrow toward therear face 2 d of the computer 1 in a manner such that the pair of guidepins or arms 18 a, 18 b are fitted individually in the recesses of therespective interface apertures 4 a, 4 b by operation of a swingableoperating lever 29. Such engagement of the guide arms 18 a, 18 b withthe respective interface apertures 4 a, 4 b fine tunes the positioningof the pins (or pin receptors) 15 a of the expansion connector 15relative to the pin receptors (or pins) 4 c of the computer's I/Oconnector 4. Continued operation of the operating lever 29 continuesmovement of the expansion connector 15 toward the computer's I/Oconnector 4, and engages the pins (or pin receptors) 15 a with the pinreceptors (or pins) 4 c during final insertion.

As a result, the expansion connector 15 of the docking station 13 isconnected to the computer's I/O connector 4. Additionally, the computer1 cannot be removed from the docking station 13 because the guide pinsor arms 18 a, 18 b engaging the interface apertures 4 a, 4 b conspirewith the receiver structure 27 engaging the computer casing's tongue 2g, and the locating pins 23 a and 23 b engaging the mating locatingholes 6 a and 6 b in the bottom surface 2 a of the computer casing 2 tosecure the computer 1 relative to the docking station's connectorpresentation surface 21 and the bearing surface 19, respectively.

In removing the computer from the docking station apparatus 13, theoperating lever 29 is reversed to move the expansion connector 15 awayfrom the computer rear surface 2 d, whereby the expansion connector 15is disconnected from the computer's I/O connector 4, and the guide pinsor arms 18 a, 18 b are disengaged from the respective interfaceapertures 4 a, 4 b. The computer casing 2 can be rotated about thetongue 2 g so that the bottom surface 2 a of the casing 2 is disengagedfrom the bearing surface 19, and the computer 1 is disengaged from thedocking station 13.

In the docking station apparatus 13 described above, the pins (or pinreceptors) 15 a of the expansion connector 15 are attached to a circuitboard which is located within a casing 31 of the apparatus 13, and theexpansion connector 15 is connected to the circuit board through aflexible wiring harness. The flexible wiring board is in turn connectedthrough other flexible wiring harnesses to separate and individual modemconnector, a game port, audio speaker connectors, a microphoneconnector, two serial connectors, a parallel connector, a display unitconnector, a USB connector, a mouse connector, a keyboard connector, andan external power supply connector, as are generally well-known in theart.

FIG. 4 illustrates an input/output (I/O) plate 33 of the docking station13 where the flexible wiring harnesses of external devices may beconnected to, for example, a mouse connector 35, a keyboard connector37, a display unit connector 39, one or more serial connectors 41, agame port 43, a parallel connector 45, a serial connector 47, one ormore USB connectors 49, a microphone connector 51, one or more speakerconnectors 53, an external power supply connector 55, a modem connector57, or a power switch 59.

However, known docking station apparatus are limited in their ability toprovide the above expansion efficiently and reliably.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENT

In the Figures, like numerals indicate like elements.

FIG. 5 is a front perspective view that illustrates the presentinvention embodied by example and without limitation as a novel externalcomputer expanding apparatus or “docking station” 100 which is adaptedto be interposed between a portable computer of the type illustrated inFIGS. 1-3 and a plurality of peripheral devices and relay signalstransferred between the computer and the devices.

The docking station 100 includes a two-piece body 102 having an upperbody portion 102 a connected to a lower body portion 102 b along a line103 of mutual contact. The upper body portion 102 a is formed with abearing surface 104 on one face of a substantially rigid bearing plate105. The bearing surface 104 is structured for the computer casing 2 tobe removably placed thereon. A connector presentation surface 106 isprojected above the bearing surface 104 for presenting an expansionconnector 108 to the rear face 2 d of the computer 1 when the computer'sbottom face 2 a is placed on the bearing surface 104. The upper bodyportion 102 a also includes means for securing the computer 1 to thebearing surface 104 in fixed position relative to the connectorpresentation surface 106 such that a coupling with the expansionconnector 108 is not interrupted unintentionally. By example and withoutlimitation, the securing means includes a receiver structure 110 fixedlypositioned adjacent to a front portion 111 of the bearing surface 104opposite from the connector presentation surface 106 and having an openjaw structure 112 facing toward the connector presentation surface 106and structured to receive and mate with the tongue 2 g on the front faceof the computer casing 2. Mating of the tongue 2 g within the open jaw112 of the receiver structure 110 resists separation of the computercasing's bottom face 2 a from the bearing surface 104. Such mating ofthe tongue 2 g within the jaw 112 of the receiver structure 110 alsoresists sliding of the computer casing 2 along the bearing surface 104away from the connector presentation surface 106. Additionally, the openjaw 112 may optionally include lips on either side thereof that engageside surfaces 2 k and 2 l (if present) of the tongue 2 g, and by suchengagement, resist sideways slippage along the bearing surface 104parallel of the connector presentation surface 106.

The securing means also includes a pair of engaging pins 114 a and 114 bfixedly positioned on a rear portion 115 of the bearing surface 104adjacent to the connector presentation surface 106, the engaging pins114 a, 114 b are structured to be slidingly received into the matinglocating holes 6 a and 6 b in the bottom surface 2 a of the casing 2.The two engaging pins 114 a and 114 b operate to position the computercasing 2 relative to the docking station bearing surface 104, and inparticular to position the computer's I/O connector 4 relative to thedocking station's expansion connector 108. Such mating of the twoengaging pins 114 a, 114 b within the respective locating holes 6 a, 6 balso serve to resist both lateral and longitudinal slippage of thecomputer casing 2 relative to the bearing surface 104. The two engagingpins 114 a, 114 b resist both sliding of the computer casing 2 along thebearing surface 104 away from the connector presentation surface 106,and simultaneously resist sideways slippage along the bearing surface104 parallel of the connector presentation surface 106.

The securing means also includes a pair of guides 116 a and 116 bprovided as either substantially rigid pins or stiff arms that arepositioned on opposite sides of the expansion connector 108. The guides116 a and 116 b extend past the expansion connector 108 and engage theapertures 4 a and 4 b on opposite sides of the computer's I/O connector4 in advance of the expansion connector 108 engaging the computer's I/Oconnector 4. As is discussed in detail below, by operation of a slidingexpansion connector drive mechanism 118, the expansion connector 108simultaneously with the pair of guide pins or arms 116 a, 116 b(hereinafter “guide arms”) on either side of the expansion connector 108are together moved inward from the presentation surface 106 (in thedirection indicated by arrow 120) across the bearing surface 104 towardthe opposing open jaw 112 of the receiver structure 110 in a manner suchthat the pair of guide arms 116 a, 116 b are fitted individually in therecesses of the respective interface apertures 4 a, 4 b the rear face 2d of the computer casing 2 in advance of connection of the connector 108with the computer's I/O connector 4. Such engagement of the guide arms116 a, 116 b with the respective interface apertures 4 a, 4 b pressesthe pair of guide arms 116 a, 116 b against the respective interfaceapertures 4 a, 4 b in the rear face 2 d of the computer casing 2, whichin turn pushes the front face 2 c toward the receiver structure 110 andthe tongue 2 g into its open jaw 112. Additionally, the mating of theguide arms 116 a, 116 b within the respective computer casing interfaceapertures 4 a, 4 b resist sideways slippage along the bearing surface104 parallel of the connector presentation surface 106. Moreimportantly, the mating of the guide arms 116 a, 116 b within therespective computer casing interface apertures 4 a, 4 b resistsseparation of the computer casing's bottom face 2 a from the bearingsurface 104 so that the two engaging pins 114 a, 114 b within therespective locating holes 6 a, 6 b more effectively resist both lateraland longitudinal slippage of the computer casing 2 relative to thebearing surface 104.

Furthermore, the expansion connector 108 includes a quantity of pinreceptors or pins (shown) 122 organized in a selected pattern to engagethe pins or pin receptors 4 c of the computer's I/O connector 4.Accordingly, such engagement of the guide arms 116 a, 116 b on eitherside of the expansion connector 108 with the respective interfaceapertures 4 a, 4 b also fine tunes the positioning of pin receptors orpins (shown) 122 of the expansion connector 108 relative to the pinreceptors (or pins) 4 c of the computer's I/O connector 4, wherebyoperation of the expansion connector drive 118 causes the expansionconnector 108 to engage the computer's I/O connector 4, and engages thepins (or pin receptors) 122 with the pin receptors (or pins) 4 c.

Thus, the three-part computer securing means includes the receiverstructure 110 fixed adjacent the front portion 111 of the bearingsurface 104, the engaging pins 114 a and 114 b fixed on the rear face115 of the bearing surface 104, and the guide arms 116 a, 116 b oneither side of the expansion connector 108, which operate together toretain the computer's I/O connector 4 on the rear face 2 d of the casing2 in uninterrupted engagement with the docking station's expansionconnector 108.

However, the guide arms 116 a, 16 b on either side of the expansionconnector 108 might interfere with seating the computer casing 2 againstthe bearing surface 104, so a sensing means 123 is optionally providedfor sensing that the computer's casing 2 is emplaced on the dockingstation's bearing surface 104 with its I/O connector 4 positioned toreceive the docking station's expansion connector 108. For example, theoptional sensing means 123 may be provided in the form of safety catch124 having a stem or button that cooperates with the expansion connectordrive 118 to detect presence of the computer 1 against the bearingsurface 104. As discussed herein below, if present, the sensing means123 is an optional safety mechanism that prevents the expansionconnector drive 118 from being operated unless the computer casing 2 isfirmly seated against the bearing surface 104 of the docking stationupper body portion 102 a, which depresses the safety catch 124. Thus,the docking station 100 optionally senses the presence of the computer 1when installation of the casing 2 causes depression of the safety catch124, if present. By requiring previous operation of the safety catch124, if present, the expansion connector 108 cannot be deployed untilthe computer's I/O connectors is positioned to receive it. Accordingly,neither the guide arms 116 a, 116 b nor the expansion connector 108 caninterfere with seating the computer casing 2.

Furthermore, while the computer casing 2 is being seated, the expansionconnector 108 remains tucked safely away in a home position on thesidelines of the bearing surface 104. For example, the expansionconnector 108 is protected in a disengaged “safe” position within anintegral housing portion 126 of the casing upper body 102 a positionedat the rear 115 of the bearing surface 104, where the expansionconnector 108 is out of harm's way during seating of the computer casing2. By example and without limitation, the housing 126 extends above thebearing surface 104 and is formed with a cavity 128 that is extendedrearward of the bearing surface 104. The cavity 128 is sized to hold theexpansion connector 108 on a connector bracket 130 having guide arms 116a, 116 b projected therefrom on either side of the expansion connector108. The bracket 130, together with the expansion connector 108 andguide arms 116 a, 116 b on either side thereof, is movable (as indicatedby arrow 120) by operation of the expansion connector drive mechanism118 out of the cavity 128 and inward of the bearing surface 104 throughan opening 132 formed in the presentation surface 106 of the housing126.

The docking station 100 of the present invention optionally includes alocking latch mechanism 134 for constraining the expansion connectordrive mechanism 118 relative to the upper body portion 102 a of thedocking station 100. Accordingly, the locking latch mechanism 134constrains the bracket 130 having the expansion connector 108 and guidearms 116 a, 116 b in a deployed position, the deployed position havingthe expansion connector 108 outside the cavity 128 and extended over thebearing surface 104.

As a result, the expansion connector 108 of the docking station 100 isconnected to the computer's I/O connector 4. Additionally, the computer1 cannot be removed from engagement with the docking station 100 becausethe guide arms 116 a, 116 b engaging the interface apertures 4 a, 4 bcooperate with the receiver structure 110 engaging the computer casing'stongue 2 g, and the locating pins 114 a and 114 b engaging the matinglocating holes 6 a and 6 b in the bottom surface 2 a of the computercasing 2 to secure the computer 1 relative to the connector presentationsurface 106 and the bearing surface 104, respectively, of the dockingstation apparatus 100. The locking latch mechanism 134 ensures theexpansion connector drive mechanism 118 cannot be dislodged so that theguide arms 116 a, 116 b continue to engage the interface apertures 4 a,4 b, even if the expansion connector drive mechanism 118 is attempted tobe dislodged, either accidentally or intentionally.

In removing the computer from the docking station apparatus 100 of theinvention, the expansion connector drive mechanism 118 is reversed tomove the expansion connector 108 away from the computer rear surface 2d, whereby the expansion connector 108 is disconnected from thecomputer's I/O connector 4, and the guide arms 116 a, 116 b aredisengaged from the respective interface apertures 4 a, 4 b. Thecomputer casing 2 can be rotated about the tongue 2 g so that the bottomsurface 2 a of the casing 2 is disengaged from the bearing surface 104,and the computer 1 is disengaged from the docking station 100.

According to one embodiment of the docking station 100 of the invention,the expansion connector 108 is optionally loosely mounted on the bracket130 with a little lateral play such that the expansion connector 108 ispermitted to move relative to the bracket 130 and its pin receptors orpins (shown) 122 wiggle or “float” into final mating positions with therespective pin receptors (or pins) 4 c of the I/O connector 4 after theguide arms 116 a, 116 b have established a nominal docking position, asin the prior art. Thus, the guide arms 116 a, 116 b with the respectiveinterface apertures 4 a, 4 b fine tunes the positioning of the pins (orpin receptors) 122 of the expansion connector 108 relative to the pinreceptors (or pins) 4 c of the computer's I/O connector 4 prior to finalinsertion.

Alternatively, the expansion connector 108 is optionally securelymounted on the bracket 130 without appreciable lateral play such thatthe expansion connector 108 is not permitted to move relative to thebracket 130 and its pin receptors or pins (shown) 15 a do not wiggle orfloat into final mating positions with the respective pin receptors (orpins) 4 c of the I/O connector 4. Rather, as discussed herein below, theexpansion connector drive mechanism 118 provides sufficient lateral playthat, the guide arms 18 a, 18 b operate to establish both a nominaldocking position and a final insertion position of the expansionconnector 108 relative to the computer's I/O connector 4. Thus, thecomplexity of the prior art bracket 18, as discussed herein above, iseliminated, while the positioning function is maintained as a feature ofthe expansion connector drive mechanism 118 of the invention.

Optionally, hand clearances 137 communicate with either side of thedocking station's computer bearing surface 104 for access to the bottomsurface 2 a of the computer 1 for lifting it free of the bearing surface104 and the guide pins 114 a, 114 b projected therefrom. By example andwithout limitation, the hand clearances 137 are provided as indentationsin the upper body portion 102 a and optionally in the lower body portion102 b as well. The hand clearances 137 are located near the connectorpresentation surface 106 and the guide pins 114 a, 114 b for more easilylifting the computer 1 clear of the guide pins 114 a, 114 b and the jaw112 of the receiver structure 110 opposite.

Additionally, an edge recess 139 communicates with the docking station'scomputer bearing surface 104 and one side of the upper body portion 102a for storing a novel display unit support 142 that is structured forsupporting the computer's flat display unit 9.

A recessed throat portion 146 of the receiverstructure's jaw 112 is set back between the front portion 111 of thebearing surface 104 and the upper lip 144. The recessed throat portion146 of the jaw 112 engages the front face 2 c of the computer casing 2.

FIG. 16 is perspective view inside the upper body portion 102 a andillustrates the expansion connector drive mechanism 118 of the presentinvention as well as features of the upper body portion 102 a thatoperate with the expansion connector drive mechanism 118. By example andwithout limitation the expansion connector drive mechanism 118 is formedof a single-piece elongated frame 204 having a substantially planarinterface surface 233 (shown in one or more subsequent figures). Afollower mechanism 206 is provided by example and without limitation asan elongated lengthwise inner slot that extends substantially along alongitudinal axis L thereof for nearly the entire length of the frame204 within a retention plate 207. An integral expanded connector seat208 is positioned at a first distal or far end 210 of the frame 204 formounting the expansion connector 108 thereon.

An inner surface 224 of the upper body portion's substantially rigidbearing plate 105 opposite from the bearing surface 104 includes a guidemechanism 226 that cooperates with the inner slot 206 to guide the frame204 substantially along a drive axis DA that is substantially coincidentwith a longitudinal axis L of the slot 206. The inner slot followermechanism 206 of the frame 204 thus cooperates with the guide mechanism226 for moving the frame 204 across the inner surface 224 of the upperbody portion 102 a along the drive axis DA with the frame'ssubstantially planar interface surface 233 moving substantially parallelwith the inner surface 224 of the bearing plate 105. Here, the interiorof the guide mechanism 226 is exposed for clarity. By example andwithout limitation, the guide mechanism 226 is formed by two guides 228arranged on the upper body portion's inner surface 224 in spaced apartpositions along the drive axis DA. Optionally the guides 228 arerotating disk guides formed as wheels or rollers that rotate aboutrespective axles or hubs 232 provided on the upper body portion's innersurface 224. The axles or hubs 232 may be configured to space therotating disk guides 228 slightly away from the upper body portion'sinner surface 224 for easier rotation. By example and withoutlimitation, the two guides 228 are optionally provided as one or moreslides fixed to the inner surface 224 of the upper body portion 102 aand permit the frame 204 to slide freely along the drive axis DA. Asdescribed herein below, the frame 204 is constrained relative to theguides 228 to move across the upper body portion's inner surface 224along the drive axis DA.

When mounted on the connector seat 208 at the far end 210 of the frame204, the expansion connector 108 fits within the cavity portion 128 ofthe housing 126 and extends above the bearing surface 104 of the upperbody portion 102 a. The frame 204 is moveable, either by sliding orrolling, in cooperation with the guide mechanism 226 across the innersurface 224 of the upper body portion 102 a and along the drive axis DA.

The expansion connector drive mechanism 118 of the invention alsoprovides a small amount of lateral play (indicated by arrow 241) suchthat the connector seat 208 is permitted to move laterally relative tothe upper body portion's inner surface 224 and the bearing surface 104on the opposite surface of the bearing plate 105 and substantiallycrosswise of the drive axis DA. For example, the follower mechanism orslot 206 fits with sufficient play on the guides 228 that the frame 204is permitted sufficient lateral play along arrow 241 that lateral playthe connector seat 208 permits the expansion connector 108 securelymounted thereon to move laterally relative to the bearing surface 104 ofthe upper body portion's bearing plate 105. Thus, although is securelymounted on the bracket 130 without appreciable lateral play, theconnector seat 208 actually has sufficient lateral play through theexpansion connector drive mechanism 118 of the invention to establishboth a nominal docking position of the expansion connector 108 relativeto the computer's I/O connector 4 and a final insertion position of thepin receptors or pins (shown) 122 relative to the I/O connector's pinreceptors (or pins) 4 c. Thus, the complexity of the prior art bracket18, as discussed herein above, is eliminated, while the positioningfunction is maintained as a feature of the expansion connector drivemechanism 118 of the invention.

An integral catch mechanism 212 and integral handle 214 are bothpositioned adjacent to a second proximal or near end 216 of the frame204 opposite from the connector seat 208. The handle 214 may beprovided, by example and without limitation, on one side 218 of theframe 204, while the catch mechanism 212 may be provided, by example andwithout limitation, at the near end 216. The catch mechanism 212 isstructured to cooperate with the locking latch mechanism 134 forsecurely fixing the expansion connector drive mechanism 118 relative tothe upper body portion 102 a of the docking station 100 with the bracket130 holding the expansion connector 108 and guide arms 116 a, 116 b oneither side thereof in a deployed position, i.e., with the expansionconnector 108 outside the cavity 128 and extended over the bearingsurface 104. By example and without limitation, the frame's integralcatch mechanism 212 includes a lip portion 242 of the that engageseither the optional lock mechanism 134, or an alternative non-lockinglatch mechanism 244 (shown here), which is optionally substituted.

As illustrated here, the alternative non-locking latch mechanism 244 issubstituted for the optional locking latch mechanism 134. Thealternative non-locking latch mechanism 244 similarly constrains theexpansion connector 108 to remain in the deployed position, as describedherein. By example and without limitation, the alternative non-lockinglatch 244 is a flexible latch mechanism of the type illustrated in U.S.patent application Ser. No. 11/064,777 filed in the name of the inventorof the present invention on Feb. 23, 2005, which is incorporated hereinin its entirety. Alternatively, when present, the optional lockingmechanism 134 lockingly secures the expansion connector 108 in thedeployed position.

The sensing means 123 is provided as a security mechanism 220 that isstructured to cooperate with the safety catch 124 to resist deploymentof the expansion connector 108 until the computer 1 is seated againstthe bearing surface 104 and the computer's I/O connector 4 is positionedto receive the expansion connector 108. By example and withoutlimitation, the security mechanism 220 is provided in an integralsecurity plate 221 formed, by example and without limitation, along theside 218 of the frame 204 and spaced away from the lengthwise inner slot206, for example, between the connector seat 208 and the handle 214. Thesecurity mechanism 220 is provided as a keyhole 222 formed in thesecurity plate 221, the keyhole 222 being structured for cooperatingwith the safety catch 124 such that, when the safety catch 124 isengaged with the keyhole 222, the frame 204 cannot be moved relative tothe casing's upper body portion 102 a. Furthermore, when the safetycatch 124 is disengaged from the cooperating keyhole 222 in the securityplate 221, the frame 204 is free to move along the longitudinal axis L.

The novel expansion connector drive mechanism 118 is operated by firstdepressing the safety catch 124 relative to the bearing surface 104 ofthe upper body portion 102 a, for example by seating the bottom face 2 aof the computer casing 2 against the bearing surface 104. Depressing thesafety catch 124 simultaneously disengages the safety catch 124 of thesecurity mechanism 220 from the cooperating keyhole portion 222 in thesecurity plate 221, which thereby permits the frame 204 to move alongthe frame drive axis DA. The handle 214 of the expansion connector drivemechanism 118 is pulled along the drive axis DA toward the front face172 of the casing's upper body portion 102 a, which in turn pulls theexpansion connector 108 and the guide arms 116 a, 116 b on either sidethereof into the deployed position described herein, i.e., with theexpansion connector 108 outside the cavity 128 and extended over thebearing surface 104. The lip portion 242 of the frame's integral catchmechanism 212 engages either the optional lock mechanism 134, oralternative non-locking latch mechanism 244 (shown here), whichconstrains the expansion connector drive mechanism 118 in the deployedposition.

An optional retraction mechanism 246 is operated for retracting theexpansion connector 108 from the deployed position by driving the frame204 along the drive axis DA away from the upper body portion's frontface 172 toward its rear face 248. By example and without limitation,the retraction mechanism 246 includes a resilient biasing mechanism 250,such as a tension spring (shown), that is coupled between the rear face248 of the upper body portion 102 a and the second or near end 216 ofthe frame 204 adjacent to the handle 214. The biasing mechanism 250operates between the rear face 248 and the near end 216 of the frame 204for pulling the frame 204 toward the rear face 248. The biasingmechanism 250 thereby operates to automatically retract the expansionconnector 108 from the deployed position when the locking latchmechanism 134 or non-locking latch mechanism 244 (shown here) isoperated to release the frame's integral catch mechanism 212.Alternatively, as illustrated, the spring 250 is coupled between astanchion 251 near the rear face 248 and the near end 216 of the frame204 for retracting the expansion connector 108.

Furthermore, the resilient biasing mechanism or tension spring 250 beingmounted on one side 218 of the frame 204 offset of the drive axis DAprovides leverage to the force applied by the spring 250. Therefore, thespring 250 also biases the frame 204 on the guides 228 relative to theupper body portion's inner surface 224 crosswise of the drive axis DA.Accordingly, the spring 250 also pulls the inner slot 206 of the frame204 against the guides 228 so that the connector seat 208 and theexpansion connector 108 securely mounted thereon are biased laterallyrelative to the upper body portion's inner surface 224 and the bearingsurface 104 on the opposite surface of the bearing plate 105 andsubstantially crosswise of the drive axis DA. The lateral bias providedby the offset biasing mechanism 250 stabilizes the expansion connector108 relative to the computer's I/O connector 4 for reducing effects onthe interconnection of shocks and vibrations experienced by the dockingstation 100. The novel expansion connector drive mechanism 118 of theinvention thus further improves the interconnection of expansionconnector 108 with the computer's I/O connector 4 over the prior artdocking station's expansion connector 15, as discussed above.

As disclosed herein, the safety catch 124 will not interfere with theretraction mechanism 246 retracting the frame 204. However, anotherbiasing mechanism 252 (shown in subsequent figures) operates to resetthe sensing means for sensing that the computer's casing 2 is emplacedon the docking station's bearing'surface 104 before the expansionconnector drive 118 can be operated.

FIG. 17 illustrates the alternative non-locking latch mechanism 244 byexample and without limitation as a flexible latch mechanism of the typeillustrated in U.S. patent application Ser. No. 11/064,777, which isincorporated herein in its entirety, for latching the expansionconnector 108 in the deployed position. As illustrated here by exampleand without limitation the alternative non-locking latch mechanism 244includes a tooth 254 positioned at one end of a flexible arm 256 that isintegrally (shown) or separately attached at its opposite end to theupper body portion 102 a, such as to the front face 172 thereof.Inclined surfaces 257 and 258 cooperate to allow the to tooth 254 toautomatically engage the lip portion 242 of the frame's integral catchmechanism 212 when the frame 204 is moved into the position fordeploying the expansion connector 108, i.e., when the near end 216 ofthe frame 204 is pulled close to the front face 172 of the upper bodyportion 102 a. A handle 260 is provided on the flexible arm 256 oranother part of the alternative non-locking latch mechanism 244 fordisengaging the tooth 254 from the frame's lip portion 242, whichreleases the frame 204 for retracting the expansion connector 108 fromthe deployed position.

FIG. 18 illustrates the guide mechanism 226 that cooperates with theinner slot 206 to guide the frame 204 substantially along the drive axisDA. As discussed above, the frame 204 is constrained to move along thetwo guides 228 relative to the upper body portion's inner surface 224along the drive axis DA. Here, by example and without limitation one ormore keepers 240 are secured to the upper body portion's inner surface224 by one or more fasteners 236 for constraining the frame 204 to movealong the drive axis DA. The one or more keepers 240 also operate toconstrain the guide discs 228, when present, in a position forcooperating with the inner slot 206 of the frame 204. Other structuresfor the guide mechanism 226 are also contemplated and may be substitutedwithout deviating from the scope and intent of the present invention.For example, the one or more keepers 240 are provided by a pair ofdisk-shaped keepers, i.e., flat washers, that are secured to the upperbody portion's inner surface 224 by the fasteners 236 for constrainingthe frame 204 to move along the drive axis DA.

FIG. 19 illustrates the expansion connector drive mechanism 118 of thepresent invention as well as features of the upper body portion 102 athat operate with the expansion connector drive mechanism 118. Here, theframe 204 is shown adjacent to the rear face 248 of the upper bodyportion 102 a with the expansion connector 108 retracted from itsdeployed position. However, the security mechanism 220 is disengaged byhaving the safety catch 124 disengaged from the cooperating keyhole 222in the security plate 221 so that the frame 204 is free to move alongthe drive axis DA. As illustrated here, the biasing mechanism 252 isshown as a compression spring that operates between the safety catch 124and, for example, an inner surface 253 of the lower body portion 102 b(omitted here for clarity, shown in a subsequent figure) to drive thesafety catch 124 into security plate 221 and reset the docking station'scomputer sensing means.

FIG. 20 illustrates the expansion connector drive mechanism 118 of thepresent invention with the frame 204 is shown adjacent to the front face172 of the upper body portion 102 a with the expansion connector 108 inits deployed position extended over the bearing surface 104. Here, thebiasing mechanism 250 is shown as being in an expanded state for pullingthe frame 204 toward the rear face 248 when the security mechanism 220is subsequently disengaged. The biasing mechanism 250 thereupon operatesto retract the expansion connector 108 from the deployed position whenthe optional lock mechanism 134 is operated to release the frame'sintegral catch mechanism 212.

FIG. 21 is a section view taken substantially along a drive axis DA ofthe expansion connector drive mechanism 118. This figure illustrates thenovel guide mechanism 226 of the invention having the movable frame 204shifted toward the front face 172 of the upper body portion 102 a suchthat the integral connector seat 208 is positioned to place theexpansion connector 108 (removed for clarity) in the deployed positionrelative to the bearing surface 104. As illustrated here, the guidemechanism 226 is formed by the two guides 228 arranged on the upper bodyportion's inner surface 224 in spaced apart positions along the driveaxis DA within the cooperating inner slot 206 of the frame 204. Byexample and without limitation, the two guides 228 are illustrated hereas wheels or rollers that rotate about respective axles or hubs 232provided on the upper body portion's inner surface 224. The frame 204 isconstrained to move relative to the upper body portion's inner surface224 along the drive axis DA by a single one-piece keeper 240 that isheld in place by the two fasteners 236.

As illustrated here the optionally lock mechanism 134 constrains theexpansion connector 108 to remain in the deployed position, as describedherein.

The latch on the upper body portion 102 a, for securely fixing theexpansion connector drive mechanism 118 relative to the upper bodyportions 102 a of the docking station 100 is illustrated here as thelock mechanism 134. As illustrated, the lock mechanism 134 includes aretractable tooth 262 positioned at one end of a lock cylinder 264 thatis attached at its opposite end to the upper body portion 102 a, such asto the front face 172 thereof. An inclined lead surface 266 allows theto tooth 262 to automatically engage the lip portion 242 of the frame'sintegral catch mechanism 212 when the frame 204 is moved into theposition for deploying the expansion connector 108, i.e., when the nearend 216 of the frame 204 is pulled close to the front face 172 of theupper body portion 102 a. A key 268 is applied to a key hole 270 in thelock cylinder 264 for disengaging the tooth 262 from the frame's lipportion 242, which releases the frame 204 for retracting the expansionconnector 108 from the deployed position.

FIG. 22 illustrates the docking station 100 being in an initial state ofreadiness to accept the computer 1 (shown in phantom),with the bottomface 2 a of the casing 2 spaced away from the docking station's bearingsurface 104. Here, the expansion connector 108 is mounted on theconnector seat 208 at the far end 210 of the frame 204, and theexpansion connector 108 along with the two guide pins or arms 116 a, 116b that are positioned on opposite sides thereof are fully retractedwithin thee cavity portion 128 of the housing 126 adjacent to thebearing surface 104 at the rear face 248 of the upper body portion 102a.

As discussed herein, when the safety catch 124 of the optional sensingmechanism 123 is engaged with the keyhole 222 in the security plate 221,as shown, the frame 204 cannot be moved relative to the casing's upperbody portion 102 a and the bearing surface 104. Furthermore, theexpansion connector 108 and guide pins or arms 116 a, 116 b are likewisecannot be moved out of the cavity 128 to interfere with seating thecomputer 1. For example, a stem portion 272 of the safety catch 124projects above the bearing surface 104 where the computer 1 is to beseated. The stem 272 is sized to pass through both a narrow elongatedslot portion 274 at a distal end of the keyhole 222, and a clearancepassage 276 through the bearing surface 104. Furthermore, the stemportion 272 is cooperatively sized with the narrow slot portion 274 toslide freely along a substantial length thereof, which thus permits theframe 204 to move between the fully retracted position (shown here) andthe fully deployed position (shown in subsequent figures). The stemportion 272 of the safety catch 124 extends from a base portion 278having a shoulder 280 that is oversized relative to the passage 276 sothat the upper body portion's inner surface 224 on the backside of thebearing surface 104 operates as a stop for the safety catch 124.Furthermore, the base portion 278 of the safety catch 124 is too largeto pass through the narrow slot portion 274 of the keyhole 222. However,the keyhole 222 includes an enlarged passage 282 that communicates witha near end 284 of the slot portion 274 and is sized to pass the baseportion 278 of the safety catch 124. As discussed herein, the safetycatch 124 is structured to cooperate with the biasing mechanism 252 thatoperates to reset the sensing means for sensing that the computer'scasing 2 is emplaced on the docking station's bearing surface 104 beforethe expansion connector drive 118 can be operated. By example andwithout limitation, when the biasing mechanism 252 is a conventionalcompression spring, as illustrated here, the base portion 278 of thesafety catch 124 is structured with a cavity or pocket 286 that is sizedto admit a first end portion 288 of the spring 252 and orient the spring252 along a drive axis DS of the safety catch 124 that is by example andwithout limitation oriented substantially perpendicular to the bearingsurface 104 of the upper body portion 102 a. A second end portion 290 ofthe spring 252 is compressed against the inner surface 253 of the lowerbody portion 102 b (omitted here for clarity). Accordingly, the spring252 operates against the inner surface 253 of the lower body portion 102b to drive the safety catch 124 through the security plate 221 and thepassage 276 to project from the bearing surface 104. Thus, the dockingstation's computer sensing means 123 is set and the expansion connector108 is secure against being inadvertently deployed.

FIG. 23 illustrates the docking station 100 being in an intermediatestate of accepting the computer 1 (shown in phantom) with the bottomface 2 a of the casing 2 seated against the docking station's bearingsurface 104. Here, the expansion connector 108 is mounted on theconnector seat 208 at the far end 210 of the frame 204, and theexpansion connector 108 along with the two guide pins or arms 116 a, 116b on opposite sides thereof are still fully retracted within the cavityportion 128 of the housing 126 adjacent to the bearing surface 104 atthe rear face 248 of the upper body portion 102 a.

As discussed herein, when the bottom face 2 a of the casing 2 is seatedagainst the docking station's bearing surface 104, as shown, thecompression spring of the biasing mechanism 252 is compressed againstthe inner surface 253 of the lower body portion 102 b (shown in asubsequent figure, removed here for clarity). Accordingly, the safetycatch 124 is pushed into the passage 276 and flush with the bearingsurface 104. Simultaneously, the safety catch's base portion 278, whichis oversized relative to the narrow slot portion 274 of the keyhole 222,is pushed through the keyhole 222 and completely out of the securityplate 221. Only the stem portion 272 of the safety catch 124 now extendsthrough the narrow slot portion 274 of the keyhole 222. Thus, thedocking station's computer sensing means 123 recognizes the presence ofthe computer 1 as being firmly seated against the bearing surface 104,and the expansion connector 108 can now be safely deployed.

FIG. 24 illustrates the docking station 100 being in final state ofaccepting the computer 1 (shown in phantom) with the bottom face 2 a ofthe casing 2 seated against the docking station's bearing surface 104.Furthermore, the expansion connector 108 mounted on the connector seat208 is positioned to engage the computer's I/O connector 4. Here, theexpansion connector 108 and the two guide pins or arms 116 a, 116 b onopposite sides thereof are shown as being deployed out of the cavityportion 128 of the housing 126 of the upper body portion 102 a.Accordingly, as discussed herein, engagement of the guide pins or arms116 a, 116 b with the respective interface apertures 4 a, 4 b fine tunespositioning of the expansion connector 108 relative to the computer'sI/O connector 4, whereby operation of the expansion connector drive 118has here caused the expansion connector 108 to engage the computer's I/Oconnector 4, and has here caused the pins (or pin receptors) 122 toengage the pin receptors (or pins) 4 c.

As discussed herein, when the bottom face 2 a of the casing 2 is seatedagainst the docking station's bearing surface 104, as shown here, thecompression spring of the biasing mechanism 252 is compressed againstthe inner surface 253 of the lower body portion 102 b (shown in asubsequent figure, removed here for clarity). With the safety catch 124being pushed into the passage 276 and flush with the bearing surface104, the stem portion 272 of the safety catch 124 is freely moved alongthe narrow slot portion 274 of the keyhole 222. When only the stemportion 272 of the safety catch 124 extends through the narrow slotportion 274 of the keyhole 222, as here, the security plate 221 is movedalong the drive axis DA toward the front face 172 of the upper bodyportion 102 a for deploying the expansion connector 108. Thus, when thecomputer 1 is firmly seated against the bearing surface 104, theexpansion connector 108 can now be fully deployed (as illustrated) bymoving the frame 204 along the drive axis DA. For example, the frame'shandle 214 (shown in previous figures) is pulled toward the front face172 of the upper body portion 102 a.

The lip portion 242 of the frame's integral catch mechanism 212 is fullyengaged with the lock mechanism 134 provided on the upper body portion102 a. Accordingly, the expansion connector 108 and guide arms 116 a,116 b on either side thereof are configured in the deployed positiondescribed herein, i.e., out of the cavity 128 and extended over thebearing surface 104 for coupling with the computer 1. Until released,the lock mechanism 134 thus constrains the expansion connector 108 toremain in the deployed position, as described herein.

When present, the locking latch mechanism 134 is released by applicationof the key 268 to the key hole 270 and subsequent operation thereof.Else, the alternative non-locking latch mechanism 244 is operated byapplication of pressure against the latch handle 260.

Upon release of either the locking latch mechanism 134 or non-lockinglatch mechanism 244, the retraction mechanism 246, for example thetension spring shown, automatically retracts the expansion connectordrive mechanism 118 from its deployed position along with the expansionconnector 108. As illustrated by example and without limitation, theframe 204 is automatically retracted from the deployed position adjacentto the front face 172 of the upper body portion 102 a toward theretracted position adjacent to the rear face 248. The guide mechanism226 cooperates with the inner slot 206 to guide the frame 204 toward theretracted position substantially along the drive axis DA. Retraction ofthe frame 204 simultaneously retracts the expansion connector 108 seatedthereon from the computer 1 and into the safe position within the cavity128 of the integral housing portion 126 of the casing upper body 102 aadjacent the rear 115 of the bearing surface 104, where the expansionconnector 108 is out of harm's way during removal of the computer 1, asillustrated and discussed herein.

FIG. 25 illustrates the docking station 100 being in final state ofaccepting the computer 1 (removed for clarity). Furthermore, theexpansion connector 108 mounted on the connector seat 208 is positionedto engage the computer's I/O connector 4, as discussed herein. Here, theexpansion connector 108 and the two guide pins or arms 116 a, 116 b onopposite sides thereof are shown as being deployed out of the cavityportion 128 of the housing 126 of the upper body portion 102 a byoperation of the expansion connector drive 118, as discussed herein.

As discussed herein, when the bottom face 2 a of the casing 2 is seatedagainst the docking station's bearing surface 104, as shown in previousfigures, the compression spring of the biasing mechanism 252 iscompressed against the inner surface 253 of the lower body portion 102b. By example and without limitation, a cavity or pocket 292 is providedon the inner surface 253 of the lower body portion 102 b, the pocket 292being sized to admit the second end portion 290 of the spring 252opposite from the pocket 286 in the safety catch base portion 278, andbeing structured to cooperate with the pocket 286 in the safety catchbase portion 278 for orienting the spring 252 along the drive axis DS ofthe safety catch 124. The spring 252 is thus compressed between the twopockets 286 and 292 for driving the safety catch 124 through thesecurity plate 221 and the passage 276 to project from the bearingsurface 104. Thus, the spring 252 operates to set the docking station'scomputer sensing means 123 for securing the expansion connector 108against inadvertent deployment.

FIG. 26 and FIG. 27 are respective top and bottom perspective views thattogether illustrate one embodiment of the frame 204 portion of theexpansion connector drive 118 of the invention. Here, the single-pieceelongated frame 204 is illustrated having the elongated lengthwise innerslot 206 extending nearly the entire length thereof substantially alongthe longitudinal axis L thereof. The integral expanded connector seat208 is positioned at the first distal or far end 210 for mounting theexpansion connector 108 thereon, and includes a pattern of severalmounting holes 294 for attaching the expansion connector 108. Theintegral catch mechanism 212 and integral handle 214 portions are bothpositioned adjacent to the second proximal or near end 216 of the frame204 opposite from the connector seat 208. The handle 214 may beprovided, by example and without limitation, on one side 218 of theframe 204, while the catch mechanism 212 may be provided, by example andwithout limitation, at the near end 216. As discussed herein, the catchmechanism 212 includes the lip portion 242 that is structured tocooperate with either the locking latch mechanism 134 or alternativenon-locking latch mechanism 244 for securely fixing the expansionconnector drive mechanism 118 relative to the upper body portion 102 aof the docking station 100 with the expansion connector 108 in adeployed position. As illustrated here by example and without limitationthe lip portion 242 is integrally formed with the inclined surface 258that cooperates with the inclined surface 257 of the latch mechanism'stooth 254 for helping the to tooth 254 to automatically engage the lipportion 242 when the frame 204 is moved into the position for deployingthe expansion connector 108.

The inclined surface 258 of the lip portion 242 similarly cooperateswith the inclined surface 266 of the retractable tooth 262 of theoptional lock mechanism 134, when present. The inclined surface 258similarly helps the to tooth 262 to automatically engage the lip portion242 when the frame 204 is moved into the position for deploying theexpansion connector 108.

The security mechanism 220 is structured to cooperate with the safetycatch 124 to resist deployment of the expansion connector 108 until thecomputer 1 is seated against the bearing surface 104. Accordingly, theframe 204 includes the integral security plate 221 formed along the side218 thereof and spaced away from the lengthwise inner slot 206 betweenthe connector seat 208 and the handle 214. The keyhole 222 is formed inthe security plate 221 with the narrow slot portion 274 formedsubstantially parallel with the longitudinal axis L and having theenlarged passage 282 communicating with the proximal or near end 284thereof

The second proximal or near end 216 of the frame 204 includes means forcoupling the resilient biasing mechanism 250 for retracting theexpansion connector 108 from the deployed position along the drive axisDA. By example and without limitation, the second proximal or near end216 of the frame 204 includes a simple clearance hole 298 for couplingthe biasing mechanism 250, i.e., spring 252, between it and the rearface 248 of the upper body portion 102 a, as shown in FIG. 16. Theresilient biasing mechanism 250 thus operates between the upper bodyportion's rear face 248 and the near end 216 of the frame 204 forretracting the expansion connector drive 118 from the deployed positionwhen the locking latch mechanism 134 or alternative non-locking latchmechanism 244 is operated to release the frame's integral catchmechanism 212.

FIG. 28 is perspective view inside the upper body portion 102 a andillustrates the expansion connector drive mechanism 118 of the presentinvention having a simplified single-piece elongated frame 304 having anelongated lengthwise inner slot 306 extending nearly the entire lengthof the frame 304 substantially along a longitudinal axis LA thereof. Anintegral expanded connector seat 308 is positioned at a first distal orfar end 310 of the frame 304 for mounting the expansion connector 108thereon. An integral catch mechanism 312 and integral handle portion 314are both positioned adjacent to a second proximal or near end 316 of theframe 304 opposite from the connector seat 308. The handle 314 may beprovided, by example and without limitation, on an arm 317 extended fromone side 318 of the frame 304, while the catch mechanism 312 may beprovided, by example and without limitation, at the near end 316. Thecatch mechanism 312 is structured to cooperate with either the lockinglatch mechanism 134 or alternative non-locking latch mechanism 244 forconstraining the expansion connector 108 to remain in the deployedposition, as described herein.

The lengthwise slot 306 in the alternate frame 304 cooperates with theguide mechanism 226 on the inner surface 224 of the upper body portion102 a opposite from the bearing surface 104 for guiding the frame 304substantially along the drive axis DA, as described herein. By exampleand without limitation, lengthwise slot 306 cooperates with the twoguides 228 of the guide mechanism 226 that are arranged on the upperbody portion's inner surface 224 in spaced apart positions along thedrive axis DA. By example and without limitation, the two guides 228 areoptionally provided as one or more slides that permit the frame 304 toslide freely along the drive axis DA. Alternatively, the guides 228 areoptionally formed as wheels or rollers that rotate about respectiveaxles or hubs 232 provided on the upper body portion's inner surface224. The axles or hubs 232 may be configured to space the guides 228slightly away from the upper body portion's inner surface 224 for easierrotation. The frame 304 is constrained to move relative to the upperbody portion's inner surface 224 along the drive axis DA by one or morekeepers 240 (shown in phantom). For example, a pair of disc-shapedkeepers 240 are secured to the upper body portion's inner surface 224 byone or more fasteners 236 for constraining the frame 304 to move alongthe drive axis DA. The one or more keepers 240 also operate to constrainthe guide wheels 228, when present, in a position for cooperating withthe inner slot 306 of the frame 304. Other structures for the guidemechanism 226 are also contemplated and may be substituted withoutdeviating from the scope and intent of the present invention.

The alternate frame 304 is structured such that, when the expansionconnector 108 is mounted on the connector seat 308 at the far end 310 ofthe frame 304, it fits within the cavity portion 128 of the housing 126and extends above the bearing surface 104 of the upper body portion 102a. The alternate frame 304 is moveable, either by sliding or rolling, incooperation with the guide mechanism 226 across the inner surface 224 ofthe upper body portion 102 a and along the drive axis DA.

A security mechanism 320 is structured to cooperate with the safetycatch 124 to resist deployment of the expansion connector 108 until thecomputer 1 is seated against the bearing surface 104 and the computer'sI/O connector 4 is positioned to receive the expansion connector 108.Similar to the security mechanism 220 of the frame 204 discussed herein,by example and without limitation, the security mechanism 320 of thealternate frame 304 is provided in an integral security plate 321formed, by example and without limitation, along the side 318 of theframe 304 and spaced away from the lengthwise inner slot 306, forexample, between the connector seat 308 and the handle 314. The securitymechanism 320 is provided as a keyhole 322 formed in the security plate321, the keyhole 322 being structured for cooperating with the safetycatch 124 such that, when the safety catch 124 is engaged with thekeyhole 322, the frame 304 cannot be moved relative to the casing'supper body portion 102 a. For example, the keyhole 322 includes at adistal end thereof a narrow slot portion 324 sized to freely move thestem portion 272 of the safety catch 124 along a substantial lengththereof so that the frame 304 is permitted to move between the fullyretracted position (shown here) and the fully deployed position (shownin previous figures). The keyhole 322 also includes an enlarged passage326 that communicates with a near end 328 of the slot portion 324 and issized to pass the base portion 278 of the safety catch 124 for disarmingthe safety catch 124.

Similar to the novel expansion connector drive mechanism 118 operatedwith the frame 204, here the novel expansion connector drive mechanism118 of the invention is operated by first depressing the safety catch124 relative to the bearing surface 104 of the upper body portion 102 a,for example by seating the bottom face 2 a of the computer casing 2against the bearing surface 104. Depressing the safety catch 124simultaneously disengages the safety catch 124 of the security mechanism320 from the cooperating keyhole portion 322 in the security plate 321,which thereby permits the frame 304 to move along the frame drive axisDA. The handle 314 of the expansion connector drive mechanism 118 ispulled parallel to the drive axis DA toward the front face 172 of thecasing's upper body portion 102 a, which in turn pulls the expansionconnector 108 and guide arms 116 a, 116 b on either side thereof intothe deployed position described herein, i.e., the expansion connector108 outside the cavity 128 and extended over the bearing surface 104. Aintegral lip portion 330 of the frame's integral catch mechanism 312engages either the locking latch mechanism 134 (shown) or thealternative non-locking latch mechanism 244 provided on the upper bodyportion 102 a. The locking latch mechanism 134 (shown) or alternativenon-locking latch mechanism 244 constrains the expansion connector 108to remain in the deployed position, as described herein. As illustrated,the a retractable tooth 262 of the lock mechanism 134 automaticallyengages the lip 330 when the alternate frame 304 is moved into theposition for deploying the expansion connector 108 as discussed herein.For example, an inclined lead surface 332 on the frame's lip portion 330cooperates with the lead surface 258 to automatically engage the tooth262 of the lock mechanism 134 when the alternate frame 304 is moved intothe position for deploying the expansion connector 108.

The retraction mechanism 246 automatically retracts the expansionconnector 108 from the deployed position by pulling the frame 304 alongthe drive axis DA away from the upper body portion's front face 172toward its rear face 248. By example and without limitation, the biasingmechanism 250, such as a tension spring (shown), is coupled between therear face 248 and a simple catchment 334 at the second or near end 316of the frame 304 adjacent to the handle 314. The biasing mechanism 250operates between the rear face 248 the catchment 334 for retracting theframe 304 toward the rear face 248. The biasing mechanism 250 therebyoperates to retract the expansion connector 108 from the deployedposition when the locking latch mechanism 134 (shown) or alternativenon-locking latch mechanism 244 is operated to release the frame'sintegral catch mechanism 312.

Alternatively, a compression spring 335 is substituted for thecompression spring as the biasing mechanism 250 of the retractionmechanism 246 for automatically retracting the expansion connector 108from the deployed position. The compression spring 335 operates bypushing the frame 304 along the drive axis DA away from the upper bodyportion's front face 172 toward its rear face 248.

As disclosed herein, the safety catch 124 will not interfere withretraction of the alternate frame 304. However, the biasing mechanism252 operates to reset the sensing means for sensing that the computer'scasing 2 is emplaced on the docking station's bearing surface 104 beforethe expansion connector drive 118 can be operated.

FIG. 29 is an upside-down close-up view showing the edge mounting holes148 formed along the mutual contact line 103 between the upper and lowerbody portions 102 a, 102 b of the docking station's two-piece body 102.As discussed herein, the edge mounting holes 148 each provide novelmeans for holding for example but not limited to a square- or hex-shapedmechanical nut N with its threaded bore aligned with the respectivemounting hole 148 substantially parallel with the bearing surface 104and perpendicular to respective side faces 152 and 154 of the upper andlower body portions 102 a, 102 b. Any external device can be threadedlyattached to the body 102 by means of the shaft S of a screw or bolt Bbeing inserted into a selected one of the edge mounting holes 148 andthreaded into the bore of the nut N.

The edge mounting holes 148 are formed by a pair of mating shapes 336and 338 formed in the docking station's two-piece body 102 through themating upper and lower body portions 102 a, 102 b. The shapes 336, 338meet along the mutual contact line 103. By example and withoutlimitation, the edge mounting holes 148 are formed by a pair of matingsemi-circular holes 336 and 338 formed in the docking station'stwo-piece body 102 through the mating upper and lower body portions 102a, 102 b along the mutual contact line 103. However, the mating holes336, 338 may alternatively be different in shape from semi-circular, forexample, the holes 336, 338 may be mating rectangular shapes that form asquare hole when mated, or semi-hexagonal shapes that form a hexagonalshape when mated, or another combination of shapes that form an apertureadjacent to the mating line 103 of the upper and lower body portions 102a, 102 b, and such shapes may be substituted for the semi-circularshapes illustrated without departing from the spirit and scope of theinvention. Furthermore, the entire shape of the resultant edge mountingholes 148 may be alternatively formed in the edge of either one of theupper and lower body portions 102 a, 102 b without departing from thespirit and scope of the invention. For example, as illustrated by theedge mounting hole 148 at the far left of the figure, the edge mountingholes 148 may alternatively be formed as a generally “U” or “V” orsquare-shaped hole 336 entirely within an edge portion 340 of one of theside faces 154 of the lower body portion 102 b, or the front 172 or rearface 248, while the mating hole is entirely eliminated from the upperbody portion 102 a, and the shape 338 is an edge portion 342 of anopposite face 154, 174 or 248 of the upper body portion 102 a that isexposed by the hole 336 in the lower body portion 102 b, whereby theedge mounting hole 148 is formed by the shaped hole 336 that is closedby the mating shape 338 of the upper body portion's exposed edge portion342. Alternatively, as illustrated by the edge mounting hole 148 at thecenter of the figure, the edge mounting holes 148 may alternatively beformed as a generally “U” or “V” or square-shaped hole 338 entirelywithin the edge portion 342 of the upper body portion 102 a, while themating hole 336 is entirely eliminated from the lower body portion 102b, and the shape 336 is the edge portion 340 of the lower body portion102 b that is exposed by the hole 338 in the upper body portion 102 a,whereby the edge mounting hole 148 is formed by the shaped hole 338 thatis closed by the mating shape 336 of the lower body portion's exposededge portion 340.

Each of the edge mounting holes 148 is backed by a respective nut pocket346 formed by an open well 348. As illustrated by the cross-sectionalview of the edge mounting hole 148 and corresponding nut pocket 346, thewell 348 of the integral nut pocket 346 is formed in one of the upperbody portion 102 a or the lower body portion 102 b (shown). The well 348is generally rectangular in cross-section and extends through the bottomplane 156 of the lower body portion 102 b past the contact line 103. Thewell 348 is formed having an opening 350 formed in the bottom plane 156of the lower body portion 102 b (shown) or adjacent to the bearingsurface 104 in the upper body portion 102 a The nut pocket's well 348and opening 350 thereto are sized to admit a nut N of a desired size,such as #2, #4, #6, #8, #10, ¼ inch, or metric size nut or bolt head H.For example, the well 348 is formed by a pair of spaced apart rigid sidewalls 352 and 354 that extend inwardly of the side face 154 of the lowerbody portion 102 b and downwardly of the bottom plane 156 andsubstantially perpendicular to each. The side walls 352, 354 aresufficiently spaced to easily admit the nut N of the desired sizewithout being significantly oversized such that the nut N cannot rotatein the well 348. The side walls 352, 354 may include a slight draftangle from the opening 350 toward the contact line 103. The matingshapes 336, 338 along the contact line 103 are correspondingly sized toadmit the shaft of the bolt B sized to mate with the nut N.

FIG. 30 illustrates that an extension portion 356 of each well 348extends past the contact line 103. The extension portion 356 closes theend of the corresponding well 348. The extension portion 356 isoptionally formed integrally with the corresponding well 348, and mayoptionally be formed into a point having integral bottom walls 358 and360 that are contiguous along a corner 362 in the central bottom of thenut pocket's well 348. Additionally, the bottom walls 358, 360 mayoptionally form an included angle 363 therebetween centered about thecorner 362, the included angle 363 being constructed to mate with theangled walls of the nut N of the desired size and shape, i.e., square orhex. For example, the included angle 363 between the bottom walls 358,360 is structured to mate with the nut N such as a square or hex nut(shown), whereby the nut N is constrained from turning when torque isapplied during insertion and tightening of the screw or bolt B. Forexample, the angle 363 formed by the bottom walls 358, 360 is about 90degrees to accommodate a square nut. Alternatively, the angle 363 isabout 120 degrees to accommodate a hex nut.

The extension portion 356 of the well 348 may be integral with the sidewalls 352, 354 (shown at center and right) and extended from the upperor lower body portion 102 b (shown) past the contact line 103 toward theopposite lower or upper body portion 102 a (shown). As illustrated(center and right) the nut pockets 346 are optionally fully formed inthe selected upper body portion 102 a or lower body portion 102 b(shown). Alternatively, as illustrated by the nut pocket 340 (far left)the extension portion 356 is optionally formed in the opposing bodyportion 102 a (shown) and positioned to align with the walls 352, 354 ofthe well 348.

Each nut pocket's well 348 also includes a backing panel 364 that isoptionally integral with the well's side walls 352, 354 and is spacedaway from the side faces 152 and 154 of the upper and lower bodyportions 102 a, 102 b sufficiently to admit the nut N of desired size.The backing panel 364 is a means for constraining the nut N from backingaway from the edge hole 148 when the screw or bolt B is applied thereto.

Also illustrated here is the simplicity of operation of the nut pockets346. Here, the nut pocket 346 is operated by simply dropping the nut Nof the appropriate size through the opening 350 into the well 348corresponding to the selected edge mounting hole 148 with two of thenut's parallel sides S1 and S2 oriented substantially parallel with thewell's side walls 352, 354, as illustrated. Thereafter, the nut N fallsinto the extension portion 356 at the end of the well 348 and nestsbetween the side walls 352, 354 and the bottom walls 358, 360 of theextension 356 that combine to form the bottom of the well 348. Upon thenut N nesting in the extension portion 356 of the well 348, the nut'sthreaded bore Nb substantially automatically self-aligns with the edgemounting hole 148. Thereafter, the screw or bolt B of the appropriatesize is inserted through the corresponding hole 148 and threaded intothe nut's bore Nb for attaching a desired edge attachment.

FIG. 31 is a section view of the nut pockets 346 taken from inside thetwo-piece body 102 of the docking station 100 of the invention. Here,the nut pocket 346 (far left) is illustrated having the extensionportion 356 optionally formed in the opposing body portion 102 a (shown)and positioned in alignment with the walls 352, 354 of the well 348.

This, view also illustrates two of a plurality of optional tabs 366 thatextend between the upper and lower body portions 102 a, 102 b foralignment therebetween.

FIG. 32 is a section view of the nut pockets 346 taken from inside thetwo-piece body 102 of the docking station 100 of the invention. Here,the nut pocket 346 (far left) is illustrated having the extensionportion 356 optionally formed in the opposing body portion 102 a (shown)and positioned in alignment with the walls 352, 354 of the well 348. Thenut N is illustrated as being installed in the nut pocket 346 with thescrew or bolt B inserted through the edge mounting hole 148 and matedwith the nut N. The screw or bolt B is thereby positioned to secure anexternal object O (shown in phantom) to the sides 152, 154 of the upperand lower body portions 102 a, 102 b of the docking station 100 of theinvention.

FIG. 33 illustrates the nut N installed in the nut pocket 346 with thescrew or bolt B inserted through the edge mounting hole 148 and matedwith the nut N. The screw or bolt B is thereby positioned to secure theexternal object O (shown in phantom) to the sides 152, 154 of the upperand lower body portions 102 a, 102 b of the docking station 100 of theinvention.

FIG. 34 illustrates lower body portion 102 b with the upper body portion102 a removed for clarity. Here, the nut pockets 346 are illustrated asbeing optionally fully formed in the selected upper body portion 102 aor lower body portion 102 b (shown). The extension portion 356 of thewell 348 is integral with the side walls 352, 354 and extended from theupper or lower body portion 102 b (shown) past, the contact line 103toward the opposite lower or upper body portion 102 a (shown). The nut Nis illustrated as being installed in the nut pocket 346 with the screwor bolt B inserted through the edge mounting hole 148 and mated with thenut N.

FIG. 35 illustrates one of the edge mounting holes 148 alternativelyformed with a screw or bolt pocket 368 formed by example and withoutlimitation as a pair of mating pockets 370 and 372 (shown in asubsequent figure) integrally formed on inside surfaces 374 and 376 ofthe respective lower body portion 112 b and upper body portion 102 a andadjacent to the respective edges 340 and 342 thereof. The pocket 370 isformed by example and without limitation as a construction of integralwalls 378 interconnected along corners 380 and a backing panel 382integrated with the walls 378. The pockets 370, 372 mate along thecontact line 103 of the upper and lower body portions 102 a, 102 b insubstantial alignment with the corresponding shaped holes 336, 338 thatform the edge mounting hole 148. The screw pockets 368 are optionallyformed with a substantially square shape to accommodate a square-headscrew or bolt of a desired size, or may be formed with a substantiallyhexagonal shape (shown) to accommodate a hex-head screw or bolt of thedesired size. Each screw pocket 368 is thus structured to mate with thesquare or hex head of the screw or bolt B, whereby the screw or bolt Bis constrained from turning when torque is applied during installationand tightening of the mating nut N for securing the external object.

FIG. 36 is a section view of one of the screw pockets 368 taken frominside the two-piece body 102 of the docking station 100 of theinvention. Here, the screw pocket 368 is illustrated having the matingpockets 370 and 372 integrally formed on inside surfaces 374 and 376 ofthe respective lower body portion 102 b and upper body portion 102 a andadjacent to the respective edges 340 and 342 thereof. The mating pockets370 and 372 are illustrated with the respective backing panels 382removed for clarity. The mating pockets 370 and 372 are positioned inalignment with the shaped holes 336, 338 that form the correspondingedge mounting hole 148 (shown in previous figures). The screw pockets368 are optionally formed with a substantially square shape toaccommodate the head H of the square head screw or bolt B of a desiredsize, or may be formed with a substantially hexagonal shape (shown) toaccommodate a hex-head screw or bolt B of the desired size.

FIG. 37 illustrates the screw pocket 368 being alternatively configuredto accommodate a carriage bolt Bc (shown in phantom) wherein the pocket368 is formed having integral near and far portions 384 and 386substantially aligned with the shaped nut hole 338 (or 336), and theintegral backing panel 364. The near portion 384 adjacent to the wall152 (or 154) of the body portion 102 a (or 102 b) is formed as one halfof a square, either as an approximately 90 degree “V” shape or arectangle (shown) that is sized to accept a square base portion Bc1 ofthe carriage bolt head Bch without turning when the nut N is installedand tightened. The far portion 386 spaced away from the wall 152 of thebody portion 102 a by the depth of the near portion 384 is structured toaccept a round pan portion Bc2 of the carriage bolt Bc. By example andwithout limitation, the far portion 386 of the screw pocket 368 is a “V”shape or a rectangle shape (shown) aligned with the shaped hole 338 (or336) and sized to accept the round pan portion Bc2 of the carriage boltBc.

FIG. 38 is a section view of the screw or carriage bolt pocket 368 takenfrom inside the two-piece body 102 of the docking station 100 of theinvention. Here, the carriage bolt pocket 368 is illustrated by exampleand without limitation as having the far portion 386 of the screw pocket368 being a semi-cylindrical shape aligned with the shaped hole 338 (or336) and sized to accept the round pan portion Bc2 of the carriage boltBc.

FIG. 39 illustrates the novel display unit support 142 of the inventionthat is structured for supporting the computer's flat display unit 9.The display unit support 142 includes an elongated rigid support arm 388having a first pivot end portion 390 that is pivotally coupled to thedocking station body 102, the rigid support arm 388 being pivotal abouta pivot axis 392 in a plane 394 that is substantially parallel andadjacent to the side faces 152, 154 of the body portions 102 a, 102 band substantially perpendicular to the upper body portion's bearingsurface 104. By example and without limitations the pivot end 390 of thesupport arm 388 is coupled in a pivotal relationship with the two-piecebody 102 by a pivot mechanism 398. For example, the pivot mechanism 398operates about the pivot axis 392 between a hub portion 400 of the body102 and an enlarged shoulder portion 402 at the pivot end 390 of the arm388. According to one optional embodiment of the display unit support142, the shoulder portion 402 of the support arm 388 rotates about apivot axle 404 (shown in one or more subsequent figures) that is alignedalong the pivot axis 392 and extends between a hub portion 400 of thebody 102 and the arm's shoulder portion 402. Alternative embodiments ofthe pivot mechanism 398 may be substituted without departing from thespirit and scope of the invention.

The support arm 388 is constrained to operate about the pivot mechanism398 with the shoulder portion 402 abutting the body's hub portion 400 bythe pivot mechanism 398. By example and without limitation, the axle 404is optionally a screw or bolt passed through one of the edge mountingholes 148 of the type described herein and threaded into a nut 406(shown in one or more subsequent figures) in one of the nut pockets 346of the type described herein. Thereafter, a knob or handle 408 on theaxle 404 is operated for tightening and loosening of the shoulderportion 402 of the support arm 388 vis-à-vis the hub portion 400 of thebody 102 by turning relative to the nut 406 in the nut pocket 346 of thebody 102. Thus, the handle 408 on the head portion 410 of the axle 404operates against an outside face 412 of the shoulder portion 402 of thesupport arm 388 to compress the shoulder portion 402 against the body'shub 400. Accordingly, friction between the shoulder portion 402 and thehub 400 caused by tightening of the handle 408 on the head portion 410of the axle 404,constrains the support arm 388 to remain in a selectedrotational orientation with the upper body portion's bearing surface104. The display unit support 142 thus constrains the computer's flatdisplay unit 9 in the selected rotational orientation. The rotationalorientation of the support arm 388 of the display unit support 142 withthe upper body portion's bearing surface 104 is thus infinitelyadjustable by alternately loosening and tightening the handle 408.

The novel display unit support 142 of the invention also includes anovel display unit clamping mechanism 414 adjacent to a second extremesupport end portion 416 of the rigid support arm 388 opposite from thefirst pivot end portion 390. By example and without limitation, thedisplay unit clamping mechanism 414 adjacent to the second support endportion 416 of the support arm 388 is structured as a spring-loaded vicefor constraining the display unit 9 relative to the support end portion416 of the support arm 388. Accordingly, the display unit 9 is pinchedbetween an integral substantially rigid anvil 418 and a separate androtatable substantially rigid jaw 420. By example and withoutlimitation, the clamping mechanism 414 includes the substantially rigidanvil 418 being integral with the elongated support arm 388. Thesupporting anvil 418 is extended laterally to a longitudinal axis 422 ofthe support arm 388 to an extent 423 that at least an end portion 424 ofthe anvil 418 distal from the support arm 388 is projected into space ina position opposite from a portion of the bearing surface 104 in thevicinity of either one of the pair of fixedly positioned engaging pins114 a and 114 b (shown) and spaced away from the computer bearingsurface 104 by several inches. The anvil 418 is formed with an arcuatesupport surface 426 that is curved in a convex shape covering anextended arc having a substantially smooth face aligned generally withthe longitudinal axis 422 of the elongated support arm 388 and facingtoward the front face 172 of the body 102 a such that the hard shellbacking portion 9 b of the display unit 9 is supported in an uprightposition relative to the keyboard 7 on the top face 2 b of the computercasing 2 by resting against the arcuate support surface 426 of the anvil418, as illustrated herein.

The separate substantially rigid jaw 420 includes a first proximatebarrel-shaped knuckle portion 428 that is projected inward of asubstantially rigid finger 430. The knuckle portion 428 of the jaw 420is coupled to the anvil 418 adjacent to a heal portion 432 thereofproximate to the end portion 416 of the support arm 388. The knuckleportion 428 spaces the rigid finger 430 away from the arcuate supportsurface 426 of the anvil 448 by a variable short distance 434 that isadjustably configured to permit the flat display unit 9 of the computer1 to fit therebetween. The short distance 434 by which the finger 430 isspaced away from the arcuate support surface 426 of the anvil 418 isadjustable to accept therebetween different thicknesses t of flatdisplay units 9 of different computers 1 (illustrated in FIG. 1). Theshort distance 434 is also variable as discussed herein to permit thefiat display units 9 to rotate to different orientations with thekeyboard 7 on the top face 2 b of the computer casing 2, while remainingconstrained against the arcuate support surface 426 of the anvil 418 bythe jaw 420.

Furthermore, an integral hard nub or button 436 (more clearly shown inone or more subsequent figures) is optionally projected slightly from aninward facing surface 438 of the rigid finger 430 adjacent to a secondend 440 thereof distal from the first proximate knuckle portion 428thereof. The jaw 420 is thus positioned in a pinching relationship tothe anvil 418 such as to capture the display unit 9 between the arcuatesupport surface 426 of the anvil 418 and the nub 436 projected from thedistal end 440 of the rigid finger 430. Thus, the display screen surfaceportion 9 a of the display unit 9 is supported in an upright positionrelative to the keyboard 7 on the top face 2 b of the computer casing 2by the rigid jaw 420, as illustrated herein. Accordingly, the displayunit 9 of the computer 1 is constrained from falling backward away fromthe keyboard 7 by the anvil 418, and is simultaneously constrained fromfalling forward toward the keyboard 7 by the jaw 420.

The display unit clamping mechanism 414 also includes a variablepressure resilient biasing mechanism 442 (detailed in a subsequentfigure) that resiliently biases the jaw 420 toward the arcuate supportsurface 426 of the anvil 418 in the pinching relationship describedherein. By example and without limitation, the biasing mechanism 442automatically varies the spacing distance 434 to accommodate the varyingcross-sectional thickness of the display unit 9 of the computer 1 of theprior art as the display unit 9 is rotated relative to the top face 2 bof the computer casing 2 about its hinge axis h into different uprightpositions at the back of the keyboard 7.

FIG. 40 illustrates the novel display unit support 142 of the inventionin a stored position having the support arm 388 rotated about the pivotaxis 392 toward the bearing surface 104 of the upper body portion 102 a,and the anvil 419 is nested in the edge recess 139. The edge recess 139is sized such that the anvil 418 is nested below the bearing surface 104so as not to interfere with seating of the computer 1. The knob 408 maybe tightened to secure the support arm 388 in the stored position.

FIG. 41 is a side view that illustrates the jaw 420 of the display unitsupport 142 of the invention being rotated about a drive axis 444 of thebiasing mechanism 442 into substantial alignment with the support arm388 during storing of the display unit support 142. When rotated intothis rest position, the jaw 420 does not interfere with nesting of theanvil 418 in the edge recess 139.

FIG. 42 illustrates the docking station 100 of the invention with thenovel display unit support 142 in an active position having the supportarm 388 rotated about the pivot axis 392 with the display unit clampingmechanism 414 supporting the display unit 9 in an open upright positionrelative to the keyboard 7 on the top face 2 b of the computer casing 2.Accordingly, the anvil 418 is positioned supporting the hard shellbacking portion 9 b of the display unit 9. Here, the jaw 420 isillustrated as being rotated about the drive axis 444 into substantialalignment with the support arm 388. Accordingly, the jaw 420 does notinterfere with closing the display unit 9 over the top face 2 b of thecomputer casing 2. The knob 408 may be tightened to secure the supportarm 388 in the active position.

FIG. 43 illustrates the docking station 100 of the invention with thenovel display unit support 142 in an active position having the supportarm 388 rotated about the pivot axis 392 with the display unit clampingmechanism 414 supporting the display unit 9 in an open upright positionrelative to the keyboard 7 on the top face 2 b of the computer casing 2.Here, the anvil 418 is positioned supporting the hard shell backingportion 9 b of the display unit 9. Furthermore, the jaw 420 isillustrated as being rotated into its active position supporting thedisplay screen surface portion 9 a of the display unit 9 in the uprightposition relative to the keyboard 7 on the top face 2 b of the computercasing 2. The display unit 9 is thus constrained in the upright positionby the pincer action of the jaw 420 relative to the anvil 418. Asillustrated, the button 436 at the second end 440 of the inward facingsurface 438 of the rigid finger 430 presses against the display screensurface portion 9 a of the display unit 9.

Furthermore, as illustrated here, the second end 440 of the rigid finger430 extends sufficiently from the jaw 420 that the button 436 on theinward facing surface 438 thereof is extended over the hard shell lipportion 9 c of the display unit 9 onto the display screen 9 d. The rigidfinger 430 thus wraps around the hard shell lip portion 9 c of thedisplay unit 9, and the button 436 thus falls below the lip portion 9 conto the display screen 9 d. Accordingly, the novel display unitclamping mechanism 414 is constrained from slipping laterally off of thelip portion 9 c and inadvertently releasing the display unit 9.

FIGS. 44 through 50 illustrate that the arcuate support surface 426 ofthe anvil 418 permits the backing portion 9 b of the display unit 9 toroll thereabout in smooth substantially constant contact during rotationrelative to the keyboard 7 on the top face 2 b of the computer casing 2.Simultaneously therewith the rigid jaw 420 constrains the display unit 9to follow rotations of the support arm 388 about the pivot axis 392. Forexample, the integral hard nub or button 436 on the tip 440 of the rigidfinger 430 presses against the display screen 9 d and forces the displayscreen surface 9 a toward the arcuate support surface 426 of the anvil418.

FIG. 44 also illustrates the docking station 100 of the invention withthe novel display unit support 142 in the active position of FIG. 43,having the support arm 388 rotated about the pivot axis 392 with thedisplay unit clamping mechanism 414 supporting the display unit 9 in anopen upright position relative to the keyboard 7 on the top face 2 b ofthe computer casing 2. Here, the anvil 418 is positioned supporting thehard shell backing portion 9 b of the display unit 9, while the jaw 420is positioned supporting the display screen surface portion 9 a. Thedisplay unit 9 is thus constrained in the upright position between thejaw 420 and the anvil 418.

FIG. 45 is a side view of the docking station 100 having the displayunit support 142 in one active position, as illustrated in previousfigures, having the support arm 388 rotated about the pivot axis 392with the display unit clamping mechanism 414 supporting the display unit9 in one open over-center position relative to the keyboard 7 on the topface 2 b of the computer casing 2. In this active over-center position,the anvil 418 is positioned supporting the hard shell backing portion 9b of the display unit 9. The jaw 420 is rotated into its active positionsupporting the display screen surface portion 9 a of the display unit 9in the upright over-center position relative to the keyboard 7 on thetop face 2 b of the computer casing 2. The display unit 9 is thusconstrained in the open over-center position by the pincer action of thejaw 420 relative to the anvil 418.

FIG. 46 is an opposite side view of the display unit support 142 in theactive position of FIG. 45 for constraining the display unit 9 in theopen over-center position by the pincer action of the jaw 420 relativeto the anvil 418. Here, the knob 408 is tightened to secure the supportarm 388 in the active over-center position.

FIG. 47 is a side view of the docking station 100 having the displayunit support 142 in another active position having the support arm 388rotated about the pivot axis 392 with the display unit clampingmechanism 414 supporting the display unit 9 in a substantially verticalupright position relative to the keyboard 7 on the top face 2 b of thecomputer casing 2. In this active upright position, the anvil 418 ispositioned supporting the hard shell backing portion 9 b of the displayunit 9. The jaw 420 is rotated into its active position supporting thedisplay screen surface portion 9 a of the display unit 9 in the uprightposition relative to the keyboard 7 on the top face 2 b of the computercasing 2. The display unit 9 is thus constrained in the upright positionby the pincer action of the jaw 420 relative to the anvil 418.

FIG. 48 is an opposite side view of the display unit support 142 in theactive position of FIG. 47 for constraining the display unit 9 in thesubstantially vertical upright position by the pincer action of the jaw420 relative to the anvil 418. Here, the knob 408 is tightened to securethe support arm 388 in the upright position.

FIG. 49 is a side view of the docking station 100 having the displayunit support 142 in another active position having the support arm 388rotated about the pivot axis 392 with the display unit clampingmechanism 414 supporting the display unit 9 in another open positionhaving the display unit 9 in an extreme over-center upright positionrelative to the keyboard 7 on the top face 2 b of the computer casing 2.In this active extreme over-center position, the anvil 418 is positionedsupporting the hard shell backing portion 9 b of the display unit 9. Thejaw 420 is rotated into its active position supporting the displayscreen surface portion 9 a of the display unit 9 in the extremeover-center open position relative to the keyboard 7 on the top face 2 bof the computer casing 2. The display unit 9 is thus constrained in theextreme over-center open position by the pincer action of the jaw 420relative to the anvil 418.

FIG. 50 is an opposite side view of the display unit support 142 in theactive position of FIG. 49 for constraining the display unit 9 in theextreme over-center open position by the pincer action of the jaw 420relative to the anvil 418. Here, the knob 408 is tightened to secure thesupport arm 388 in the extreme over-center position.

FIG. 51 illustrates by example and without limitation the pivotmechanism 398 that constrains the support arm 388 to operate about thepivot axis 392 with the shoulder portion 402 abutting the body's hubportion 400. By example and without limitation, when the pivot axle 404is a screw or bolt such as a shoulder bolt, it includes a first threadedend 450 that is sized to pass through none of the body's edge mountingholes 148 of the type described herein. The threaded end 450 of thescrew or bolt type pivot axle 404 is threaded into the nut 406 installedin one of the nut pockets 346 of the type described herein wherein thenut 406 is optionally a lock nut of the hex variety. Additionally, ashaft portion 452 of the screw or bolt type pivot axle 404 passesthrough a complementary rotational clearance bore 454 which is formedthrough the shoulder portion 402 of the support arm 388 and which issized to rotate smoothly about the pivot axle shaft portion 452. Thehead portion 410 of the screw or bolt type pivot axle 404 distal fromthe body 102 is by example and without limitation constrained in arecessed nut pocket 456 formed in the knob or handle 408. The knob 408constrains the head portion 410 of the pivot axle 404 for tightening andloosening of the shoulder portion 402 of the support arm 388 vis-à-visthe hub portion 400 of the body 102 by turning relative to the nut 406in the nut pocket 346 of the body 102. Thus, the handle 408 on the headportion 410 of the pivot axle 404 operates against the outside face 412of the shoulder portion 402 of the support arm 388 to compress an insideface 458 the shoulder portion 402 against an outside face 460 of the hub400. Accordingly, friction between the inside face 458 the shoulderportion 402 against an outside face 460 of the hub 400 constrains thesupport arm 388 to remain in a selected rotational orientation with theupper body portion's bearing surface 104, whereby the display unitsupport 142 constrains the computer's flat display unit 9 in theselected rotational orientation. The rotational orientation of thesupport arm 388 of the display unit support 142 is thus infinitelyadjustable relative to the upper body portion's bearing surface 104.

Alternative embodiments of the pivot mechanism 398 may be substitutedwithout departing from the spirit and scope of the invention.

FIG. 52 illustrates by example and without limitation one alternativeconfiguration of the pivot mechanism 398 wherein the head portion 410 ofthe screw or bolt type pivot axle 404 is constrained in the one of thebody's nut pockets 346. The shaft portion 452 of the pivot axle 404passes through the body's edge mounting holes 148 and extends throughthe complementary rotational clearance bore 454 which is formed throughthe shoulder portion 402 of the support arm 388. The threaded end 450 ofthe pivot axle 404 is threaded into a complementary threaded bore 462 inthe knob 408, which is operable for tightening and loosening of theshoulder portion 402 of the support arm 388 vis-à-vis the hub portion400 of the body 102 by turning relative to the pivot axle 404.

FIG. 53 illustrates by example and without limitation anotheralternative configuration of the pivot mechanism 398. For example, anoptional resilient biasing mechanism 470 may be provided for biasing theshoulder portion 402 of the support arm 388 toward the face 460 on thehub portion 400 of the body 102. By example and without limitation, theoptional resilient biasing mechanism 470 may be formed of a conventionalcompression spring 472 installed inside an enlarged counter-bore 474formed in the shoulder portion 402 through an opening 476 in the outsideface 412 of the shoulder portion 402. The spring portion 418 of thebiasing mechanism 470 is constrained between a floor portion 478 of thecounter-bore 420 and the head portion 410 of the screw or bolt typepivot axle 404. Optionally, a washer 480 may be inserted between thebolt head 410 and the compression spring 472. The spring portion 418 ofthe biasing mechanism 470 thus operates against the floor portion 478 ofthe counter-bore 474 to compress the inside face 458 of the shoulderportion 402 of the support arm 388 against the outside face 460 of thebody's hub portion 400.

Alternative embodiments of the resilient biasing mechanism 470 may besubstituted without departing from the spirit and scope of theinvention.

Additionally, a ratcheting mechanism 482 is optionally provided forsecuring the support arm 388 in rotational relationship with the bearingsurface 104 of the body portion 102 a. By example and withoutlimitation, a first quantity of one or more teeth 484 are provided onthe outside face 460 of the hub 400 portion of the body 102 in avariable intermeshing relationship with a quantity of one or morenotches 486 formed on the inside face 458 the arm's shoulder portion402. The intermeshing teeth 428 and notches 430 permit the arm to besecured in a desired rotational relationship with the body 102 forsupporting the computer's display unit 9 in a desired discreteorientation relative to the docking station's computer bearing surface104.

FIG. 54 illustrates by example and without limitation the novel displayunit clamping mechanism 414 of the display unit support 142 of theinvention in an active configuration clamping the display unit 9 in anopen position relative to the computer casing 2. The novel display unitclamping mechanism 414 is positioned adjacent to a second extremesupport end portion 416 of the rigid support arm 388 opposite from thefirst pivot end portion 390. By example and without limitation, thedisplay unit clamping mechanism 414 adjacent to the second support endportion 416 of the support arm 388 is a hand for constraining thedisplay unit 9 relative to the support end portion 416 of the supportarm 388. As discussed herein, by example and without limitation, theclamping mechanism 414 includes the substantially rigid anvil 418 thatis integral with the elongated support arm 388. The anvil 418 isextended laterally to a longitudinal axis 422 of the support arm 388with its end portion 424 being projected into space in a position abovethe bearing surface 104. The arcuate support surface 426 of the anvil418 is curved in the convex shape that covers an extended arc having acenter of rotation 488 (best shown in one or more previous figures). Thecenter of rotation 488 is oriented generally parallel with pivot axis392 of the support arm 388, substantially lateral of the longitudinalaxis 422, and substantially crosswise of the drive axis 444 of thebiasing mechanism 442. The smooth arcuate support surface 426 isdirected generally toward the front face 172 of the body 102 a forsupporting the hard shell backing portion 9 b of the display unit 9.

The first proximate knuckle portion 428 of the separate jaw 420 ismovably coupled to the anvil 418 adjacent to the heal portion 432thereof. The finger portion 430 of the jaw 420 is thus spaced away fromthe arcuate support surface 426 of the anvil 418 by the variable shortdistance 434 that is adjustably configured to permit the flat displayunit 9 of the computer 1 to fit therebetween. The short distance 434 bywhich the finger portion 430 of the jaw 420 is spaced away from thearcuate support surface 426 of the anvil 418 is adjustable to acceptdifferent thicknesses of flat display units 9 of different computers 1therebetween. Furthermore, the integral hard nub or button 436 isoptionally projected slightly from the inside surface 438 of the rigidfinger 430 adjacent to its distal tip 440. The jaw 420 is thuspositioned in a pinching relationship to the anvil 418 such as tocapture the display unit 9 between the arcuate support surface 426 andthe projected nub 436 on the tip 440 of the rigid finger 430. Thus, thedisplay unit 9 is compressed against the arcuate support surface 426 ofthe anvil 418 by the hard nub 436 on the tip 440 of the rigid finger430, as illustrated herein.

The display unit clamping mechanism 414 also includes the variablepressure resilient biasing mechanism 442 that resiliently biases the jaw420 toward the arcuate support surface 426 of the anvil 418 to form thepinching relationship described herein. By example and withoutlimitation, the biasing mechanism 442 automatically varies the spacingdistance 434 to accommodate a varying cross-sectional thickness of thedisplay unit 9 as it is rotated about its hinge axis h relative to thetop face 2 b of the computer casing 2 into different upright positionsat the back of the keyboard 7.

By example and without limitation, the biasing mechanism 442 isconstructed along the longitudinal drive axis 444 that is orientedgenerally crosswise of both the longitudinal axis 422 of the support arm388 and the center of rotation 488 of the arcuate support surface 426 ofthe anvil 418. By example and without limitation, the biasing mechanism442 includes a compression spring 490 recessed inside a tubular springcavity 492 that is counter-bored in a barrel-shaped spring casing 494 ofthe heal portion 432 at the support end portion 416 of the rigid supportarm 388. The tubular spring cavity 492 is substantially aligned alongthe longitudinal drive axis 444 of the biasing mechanism 442. Thetubular spring cavity 492 has a fill size input, opening 496 at it outerend, and terminates in a floor portion 498 at its inner end. A smallerguide pin portion 500 of the heal portion 432 extends from thebarrel-shaped cavity 494 a long the longitudinal drive axis 444. Theguide pin portion 500 of the heal portion 432 is formed therethroughwith a tubular clearance bore 502 that communicates between the floor498 of the tubular spring cavity 492 and an opening 504 at the clearancebore's outer tip 506. The tubular clearance bore 502 through the guidepin portion 500 is sized to complement a pivot axle 508 such as a screwor bolt.

The barrel-shaped knuckle portion 428 of the separate jaw 420 isprojected inward of the inward facing surface 438 of the rigid finger430 along the longitudinal drive axis 444 of the biasing mechanism 442.The barrel-shaped knuckle portion 428 is formed with a complementarytubular counter-bore 510 that is sized to slidingly receive the guidepin portion 500 of the support arm's heal portion 432 through an opening512 in the end of the knuckle portion 428 distal from the rigid finger430. The pivot axle 508 is projected substantially central of thetubular counter-bore 510 from a floor 514 thereof and along thelongitudinal drive axis 444 of the biasing mechanism 442. By example andwithout limitation, an aperture or passage 516 is formed in the floor514 of the tubular counter-bore 510 and communicates with an outwardfacing surface 518 of the rigid finger 430 opposite from the inwardfacing surface 438. When the pivot axle 508 is provided as a screw orbolt, the passage 516 is sized to receive a shaft portion 520 of thescrew-type pivot axle 508, while the aperture 516 is sized to constraina head portion 522 from passing.

When the tubular counter bore 510 in the knuckle portion 428 of the jaw420 is slidingly fit over the guide pin portion 500 projected from thesupport arm's heal portion 432, the passage 516 in the floor of thetubular counter-bore 510 is substantially aligned with the tubularclearance bore 502 in the guide pin 500. The shaft 520 of the pivot axle508 is slidingly received through the passage 516, along the tubularclearance bore 502 in the guide pin portion 500 of the spring casing494, and into the tubular spring cavity 492. The compression spring 490is received over the pivot axle's shaft 520 and compressed in thetubular spring cavity 492 between the floor portion 498 at its inner endand a second end 524 of the pivot axle 508 opposite from its head 522.For example, a nut 526 and optional washer 528 are installed onto thethreaded end of the pivot axle shaft 520.

Additionally, means are provided for securing the jaw 420 relative tothe anvil 418 with the finger portion 430 positioned over the displayscreen surface 9 a of the display unit 9 opposite from the arcuatesupport surface 426. By example and without limitation, a detentmechanism 530 is provided between the guide pin portion 500 of the anvil418 and the knuckle portion 428 of the jaw 420. The detent mechanism 530may be formed by example and without limitation by one or more teeth 532sized to slide into one or more slots 534 formed between the guide pin500 and the knuckle portion 428 of the jaw 420.

As described, the variable pressure resilient biasing mechanism 442 ofthe display unit clamping mechanism 414 resiliently biases the jaw 420toward the arcuate support surface 426 of the anvil 418 in the pinchingrelationship described herein. As will be generally well understood, thecross-sectional thickness t of the display unit 9 increases anddecreases as it is rotated into different orientations relative to thekeyboard 7 on the top face 2 b of the computer casing 2, thecross-sectional thickness t varying between a minimum when the displayunit 9 is in the substantially vertical upright position illustrated inFIG. 47, and a maximum when the display unit 9 is in the extremeover-center position illustrated in FIG. 49.

Accordingly, the biasing mechanism 442 floats the rigid finger 430 alongthe longitudinal drive axis 444 over the barrel-shaped portion 494 ofthe anvil 418. The biasing mechanism 442 thus permits the clampingmechanism 414 to accommodate the varying cross-sectional thickness t ofthe display unit 9 as it is rotated into different orientations relativeto the keyboard 7 on the top face 2 b of the computer casing 2. As thedisplay unit 9 rotates from the substantially vertical upright positionillustrated in FIG. 47, the cross-sectional thickness t increases, andthe display unit 9 exerts pressure on the biasing mechanism 442, whichspreads the jaw portion 420 of the clamping mechanism 414 resilientlyaway from the anvil portion 418. However, the spring 490 exerts anopposite compression pressure that squeezes the rigid finger 430 of thejaw 420 against the display screen surface 9 a so that the display unit9 is pressed against the arcuate support surface 426 of the anvil 418.Similarly, when the display unit 9 is rotated from any non-verticalposition, such as the extreme over-center position illustrated in FIG.49, the spring 490 continues to exert the compression pressure thatsqueezes the rigid finger 430 of the jaw 420 against the display screensurface 9 a so that the display unit 9 is pressed against the arcuatesupport surface 426 of the anvil 418 even while the cross-sectionalthickness t decreases.

Furthermore, as illustrated here, the second end 440 of the rigid finger430 extends sufficiently from the jaw 420 that the button 436 on theinward facing surface 438 thereof is extended over the hard shell lipportion 9 c of the display unit 9 onto the display screen 9 d. Asdiscussed elsewhere herein, the rigid finger 430 thus wraps around thehard shell lip portion 9 c of the display unit 9. The biasing mechanism442 operating along the longitudinal drive axis 444 forces the button436 below the lip portion 9 c and against the display screen 9 d.Accordingly, the biasing mechanism 442 operates the button 436 toconstrain the novel display unit clamping mechanism 414 from slippinglaterally off of the lip portion 9 c and inadvertently releasing thedisplay unit 9.

FIG. 55 illustrates by example and without limitation the novel displayunit clamping mechanism 414 of the display unit support 142 invention ina passive configuration wherein the hard shell backing portion 9 b ofthe display unit 9 is supported by the anvil 418 portion of the supportarm 388 with the opposing jaw portion 420 in an open position relativeto the display screen surface 9 a. Accordingly, the jaw 420 includingthe finger portion 430 is rotated away from the active position over thedisplay screen surface 9 a. For example, the knuckle 428 is pulled awayfrom the anvil 418 along the longitudinal drive axis 444 until thedetent 530 disengages, i.e., until the teeth 532 slide free of the slots534. The jaw portion 420 is rotated until the finger 430 clears thedisplay unit 9. With the finger 430 in this passive configuration, thejaw 420 is freed and the compression spring 490 draws the knuckle 428toward the anvil 418 along the longitudinal drive axis 444. The teeth532 and slots 534 may be additionally configured to form the detent 530between the between the guide pin portion 500 and the knuckle portion428 for securing the jaw 420 in the passive configuration vis-à-vis theanvil 418.

Alternative embodiments of the display unit clamping mechanism 414 andbiasing mechanism 442 may be substituted without departing from thespirit and scope of the invention.

While the preferred and additional alternative embodiments of theinvention have been illustrated and described, it will be appreciatedthat various changes can be made therein without departing from thespirit and scope of the invention.
